I think you’re correct. It’s B. But the answer D is literally the same as B, so is there a “both B and D” option?
Answer:
always
Step-by-step explanation:
Indirect proof.
The solution to the equations x - 4y = 0, x - y + 3z = 3 and 2x - 3y - z = -7 is x = -4, y = -1 and z = 2
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Independent variables represent function inputs that do not depend on other values, while dependent variables represent function outputs that depends on other values.
Given the equations:
x = 4y
x - 4y = 0 (1)
Also:
x - y + 3z = 3 (2)
And:
2x - 3y - z = -7 (3)
The solution to the equation is:
x = -4, y = -1 and z = 2
The solution to the equations x - 4y = 0, x - y + 3z = 3 and 2x - 3y - z = -7 is x = -4, y = -1 and z = 2

Answer:
4mm
Step-by-step explanation:
The side length of a cube can be found using the formula given in the question.
V = S^3, with V being volume and S being the side length.
After substituting V for 64, we can solve for S to find the side length.
64 = S^3
S = 4
A - the result is a composite number
A' - the result is not a composite number
